I’m Jonatan Chaverri — a software engineer focused on blockchain infrastructure, privacy systems, and AI-powered applications.
I have 5+ years of experience building production systems across companies like IBM, HPE, and Kyndryl, working with distributed systems, cloud infrastructure, and full-stack applications.
More recently, I’ve been deeply involved in the Starknet ecosystem, contributing to open source and building products that explore privacy, ownership, and decentralized coordination.
